What are the muscles of the posterior surface?
Retroversor muscles of the femur
Internal obturator Gemellus Quadrate muscle of the thigh Gluteal muscles Tensor muscle of the fascia latae Glutofemoral muscle Piriformis
Psoas major
Origin: last thoracic vertebrae+lumbar vertebrae
Insertion: lesser trochanter of femur
Innervation: lumbar spinal nerves DOG, intercostal+femoral nerve EQUINE
Function: anteversor pelvic limb, flexor of hip joint
Iliac muscle
Origin: iliac fascia, wings of ilium
Insertion: lesser trochanter of femur
Innervation: lumbar nerves+ femoral nerve
Function: anteversor pelvic limb, flexor of hip joint
Iliopsoas muscle
Origin: last thoracic vertebrae+ lumbar vertebrae
Insertion: lesser trochanter of femur
Innervation: lumbar spinal nerves DOG, intercostal+femoral nerve EQUINE
Function: anteversor pelvic limb, flexor of hip joint
Psoas minor
Origin: last thoracic vertebrae+ lumbar vertebrae
Insertion: ilium
Innervation: lumbar spinal nerves DOG, lumbar spinal nerves+fémoral nerve EQUINE
Function: fixator and flexor lumbar spine
Articular muscle of the hip joint
Origin: hip joint capsule
Insertion:
Innervation: sciatic nerve
Function: tenses hip joint capsule
External obturator muscle
Origin: obturator foramen
Insertion: trochanteric fossa
Innervation: obturator nerve
Function: draws limb outwards
Pectineal muscle
Origin: iliopubic eminence of femur
Insertion: medial border of femur
Innervation: obturator and femoral nerve
Function: adduction
Gracilis
Origin: pelvic symphysis
Insertion: fascia of leg
Innervation: obturator nerve
Function: adduction
Adductor muscle
Origin: medial surface of pelvis
Insertion: medial border of femur
Innervation: obturator nerve
Function: adduction
